I CABINET Filed Sept. 29, 1928 s dan my ZW Patented June 7, 1932 UNITED STATEs PATENT OFFICE This invention relates to cabinets, and more articularly to cabinets which are expressly designed for use in housing radio frequency receiving sets, although equallyuseful for other purposes. E

One of the objects of the invention is to provide a cabinet of the class referred to 1n which, when the lid of the cabinet is raised to expose a radio receiving-set, the circuit is` at the same time closed to render the set operative.

A further object of the invention is to provide a cabinet in which the door is composed of a lurality of parts, some of which are hinges together and are so constructed and arranged that the mere act of lifting the door will cause the parts to be folded in a convenient manner at the top of thecabinet.

Affurther object of the invention is to provide a cabinet of attractive appearance, of simple design and wherein the front of the cabinet may be exposed for access to the enclosed receiving set by a minimum amount of eort upon the part of the operator.

Other objects, advantages and purposes of the invention will be better understood from the following detailed description, when considered in connection with the accom anying drawing illustrating a preferred orm of the cabinet.

In the drawing:

Fig. 1 is a view in front elevation, illustrating one embodiment of the invention;

Fig. 2 shows the cabinet in plan, with part of the cover removed to disclose the arrangement of the parts therebelow;

Fi 3 is a cross sectional View, on the line 3-3 ig. 1;

Fig. 4 is a cross sectional view upon the same plane of section but showing the cabinet cover in open position;

Fi 5 is a sectional detailed view illustratin t e circuit closing means;

cabinet lid is guided; and

ig. 6 is a similar view, illustrating a por- Fig. 9 is a similar view taken at right angles to Fig. 8.

The cabinet consists of a bottom portion 8, which may be supported upon suitable feet 9, and is provided with sides 12, a back 11, and a top 10, which latter is shown as hingedly connected to the back of the cabinet 11 by suitable hin es 14. l A

The mova le lid or cover of the cabinet, which may be opened and closed to disclose or conceal the interior thereof, is composed of a panel 16, connected by hinges 17 to the forward edge of the top 10; a panel 18, which is rigidly attached to the anel 16 and at right angles to the latter, and a lower panel 20, connected by hinges 21 to the panel 18. The hinges 17 are attached to the front ed e of the top 10 and connect the panel 16 wit the topv in such manner as to permitthe former of these parts to fold down, horizontally, so as to form a continuation of the to which extends when the panel 16 is closed, horizontally, so as to fill the space which would otherwise exist at the front of the top 10. When in closed position the panel 18 extends 75 downwardly in front of the cabinet, and the panel 20 in line thereof, said panels 18 and 20 constituting when closed the front of the cabinet as shown in Fig. 1.

It will be observed that the cover, constituted by the separate panels 16, 18 and 20, does not extend completely across the front of the cabinet, but only for a portion thereof leaving outside the panels portions 10'l o the cover. Partitions 22, 22, extend from S5 front to rear of the cabinet and substantially in line with the inner edges of the side extensions of the cover 10. The inner sides of these partitions are provided with diagonal grooves, 23, which receive spring-pressed pins 24, carried by the lower edges of the panel 20, said pins travelling in the grooves as the cover is raised to open position, as shown in Fig. 4, or lowered to closed position, as shown in Fig. 3, serving during such movements of the cover to truly guide the panel 20 so that the same will be confined to movements into and out of closed position and willbe prevented from being moved into the cabinet. The panel 18 is provided with 100 as housed within the cabinet.

a handle 25 which is adapted to be grasped in lifting the cover upward for opening the same or for lowering it to close the front of the cabinet. ln these operations it is simply necessary to lift the panel 18 upwardly and the cover will be truly guided in its movements from the position shown in Fig. 3 to that shown in Fig. 4. when it is fully opened, by the movement of spring-pressed pins 24 in the grooves 23. The hinge 21 is preferably a spring hinge, whereby the weight of the panel 2O is in part, at least, counterbalaneed as the same is raised from the position shown in Fig. 3 to that shown in Fig. 4.

Interiorly of the cabinet are two springmetal electrical contact making members 28, 29, which are suitably secured to the interior of the top 10, and the member 29 is herein shown as carrying a pin 30, whose upper end extends through a hole 32 and normally projects above the topsurface of the. cover and is adapted to be pressed downward by the weight of the folding cover when the same is in open position, as shown 1n Fig. 4, caus-l ing the members 29, 28, to engage, thereby completing an electrical circuit through the wires 31, which convey lcurrent to the radio receiving apparatus .40, which is herein shown be seen that when the cover is raised to fully opened position, the weight of the panels thereof upon the contact making pin 30 will automatically close the circuit for setting the receiving apparatus into operation, thereby obviating the necessity of the operation of a switch; and, conversely, when the cover is moved from open position to closed position, the resilient contact member 29 will move away from the member 28, thereby interrupting the circuit and causing the operation of the radio receiver to be suspended.

It will be noted that the several panels of the cover, 16, 18 and 20, are so connected with each other thatthey form, in effect, a flexible cover for the front ofthe cabinet, and through the instrumentality of the guiding grooves 23 and pins 24, the movements of the several parts of the cover from closed to open position, and vice versa, may be effected by a very simple movement as it is only necessary to raise the cover by upward movement applied to the handle 25 to cause the various parts of the cover to open and fold upon the top of the cabinet in the manner as shown in Fig. 4; and, by reverse movement of the handle the parts of the cover are caused similarly to move from the position shown pFig. 4, to the closed position as shown in catch 31, indicated in Fig. 4, serves to fasten the top 10 to the side walls 12 of the cabinet so as to prevent accidental opening movements of the top, at those times when such movement is not desired. This catch may be in the form of a. simple bolt 0I' any It Will thus.

movement when in either of its extreme open or closed positions, but the frictional engagement between the pins and depressions is so slight that only a small amount of force is necessary to dislodge the cover.

Changes may be made in the details of construction, or in the arrangement of the several v parts illustrated, without departing from the spirit of my invention, rovided such changes fall within the scope o the following claims.

I claim:
